英文摘要: Phenylcarbamates of cellulose (CTPC) were chemically bonded to S-aminopropyl silica gel with 4,4'-diphenylmethane diisocyanate as a spacer through the carboxyl of the glucose unit of cellulose. Their optical resolution abilities were evaluated as chiral stationary phases (CSPs) for high-performance liquid chromatography (HPLC). It was found that CTPC regioselectively bonded at 6-position to silica gel possessed a higher chiral recognition than that either regioselectively bonded at the 2-,3-positions to silica gel or non - regioselectively bonded at 2-,3- and 6-positions to silica gel. On the other hand, the CTPC was dissolved in tetrahydrofuran (THF) and coated on underivatised silica gel by evaporation under vacuum to prepare the coated-type CSP in order to compare the optical resolution abilities with the bonded-type CSPs. It was observed that bonded-type CSPs usually showed a lower resolving abilities than those of coated-type CSPs. However, the bonded-type CSPs were able to be used with eluents such as THF in which the coated-type CSPs were not able to be used because the cellulose derivatives were soluble or swollen. Benzoin was firstly separated on bonded cellulose phenylcarbamate CSP in our experiments using THF as a component of the mobile phase, which indicated that some racemates which were not or poorly separated on coated-type CSPs might be more efficiently resolved on bonded-type CSPs using THF as a component of the mobile phase.
